No-compromise, truly balanced, 2-socket blade server for
infrastructure, virtualization and enterprise business applications
Suggested uses: Front-end and mid-tier applications requiring high performance, enterprise-
class availability and extreme flexibility and power efficiency.
Today’s data center environment is tougher than ever. You’re looking to reduce IT cost,
complexity, space requirements, energy consumption and heat output, while increasing
flexibility, utilization and manageability. Incorporating IBM X-Architecture
features, the IBM
HS22 blade server, combined with the various BladeCenter chassis, can help
you accomplish all of these goals.
Reducing an entire server into as little as .5U of rack space (i.e., up to 14 servers in 7U) does
not mean trading away features and capabilities for smaller size. Each HS22 blade server offers
features comparable to many 1U rack-optimized full-featured servers: The HS22 supports up to
two of the latest high-performance or low-voltage 6-core, 4-core, and 2-core Intel
series and 5600 series processors.. The Xeon processors are designed with up to 12MB of
shared cache and leading-edge memory performance (up to 1333MHz, depending on
processor model) to help provide the computing power you require to match your business
needs and growth. The HS22 supports up to 192GB of registered double data rate III (DDR3)
ECC (Error Checking and Correcting) memory in 12 DIMM slots, with optional Chipkill
, for high performance and reliability. Selected models are planned for NEBS-3/ETSI-
The HS22 offers an option for VMware vSphere Hypervisor (formerly ESXi) preloaded on a
standard USB flash drive. It operates in a diskless configuration, offers a smaller memory
footprint, extremely high performance, and stronger security, making getting a system up and
running in a virtualized environment faster and easier than ever before.
An integrated dual-port Gigabit Ethernet
controller is standard, providing high-speed data
transfers and offering TOE (TCP Offload Engine) support, load-balancing and failover
capabilities. Via optional expansion cards, each blade can also connect to additional Ethernet,
SAS, Fibre Channel, iSCSI, InfiniBand
and other high-speed communication switches
housed in the chassis. Optional 2-port and 4-port Expansion Cards add additional fabrics to
the HS22 server as needed. This blade is designed with power management capability to
provide the maximum uptime possible for your systems. In extended thermal conditions or
power brownouts, rather than shut down completely, or fail, the HS22 automatically reduces the
processor frequency to maintain acceptable thermal and power levels.
All HS22 models offer impressive features at an equally impressive price, including up to two
hot-swap SAS or SATA hard disk drives or two hot-swap solid-state drives with RAID-
0/1/1E support, and one USB-based internal flash drive (for embedded hypervisor]. Additional
storage is available via the BladeCenter S chassis. Moreover, the HS22 is optimized for
diskless operation, offering each blade server access to essentially unlimited external storage
capacity via Fibre Channel, SAS, or iSCSI.
A single BladeCenter E or BladeCenter H chassis supports up to 14 hot-swappable 30mm-
wide HS22 blades in only 7U (BladeCenter E) or 9U (BladeCenter H) of rack space or up to 12
in the 12U BladeCenter HT high-speed telecommunications chassis. In addition to the blade
servers, these chassis also hold up to 4 switches (BladeCenter E) or up to 10 (BladeCenter H)
or 8 switches/bridges (BladeCenter HT) internally. The BladeCenter S, designed for SMB and
mid-market customers, takes integration and affordability to a new level, combining up to 12
hot-swap SAS/SATA HDDs (with optional SAS card) and up to 6 blade servers and 4
switches. Not only can this save significant data center space (and therefore the cost of floor
space and rack hardware) compared to 1U servers, it also consolidates switches/bridges and
cables for reduced complexity and lower cabling costs, and it allows clients to manage
Chipkill protection on the HS22 requires x4 DIMMs; Chipkill protection is not available with x8 DIMMs.
Actual data transfer speed will vary and is often less than the maximum possible. Gigabit Ethernet transfer speed requires support on both
system and server, and appropriate network infrastructure.
